Abstract
This article provides a brief but comprehensive overview of microfinance academic literature with emphasis on recent innovations, trends and efficiency. In particular, we focus on controversial issues of microfinance, such as commercialization, regulation, interest rate policy and the balance between outreach and performance of MFIs.
In summary, the findings of the reviewed literature underline the great improvement in the microfinance field that, however, has not reached its full potential yet. At the same time, we outline potential risks and drawbacks which are being discovered along the way of microfinance development and maturing, many of which still waiting for more rigorous scholarly examination.
